HEATING-SYSTEM ATTAoHMEnT ronnANGEs.

To ZZ "whom t may concern:

Be it known that I, ROBERT DE POLO, a

citizen of the United States, `-residing aty Connellsville, inl the county of Fayette, State of Pennsylvania, have invented la new and useful Heating-System Attachment for Ranges; and I d o hereby declare the following to be a full, clear, and exact. description of the invention, such as will enable others skilled in the art to which it appertains to make 'andpuse the saine. f-

This invention relates to a new and useful heating system for use in connection with a cooking range or stove, whereby the heat, derived from the range or stove, may pass through the. various flues of the system. for heating purposes-at rvarious places remote from the range.

One ofthe objects of the'invention is to provide meansl whereby the various flues of the system may be cleaned.

In practicaliields, the details of construction may necessitate alterations, -falling within the scope of what is claimed.

The .invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a view in front elevation and partly in section of a portion of the heatingvsystem that is adjacent the range or stove. Fig. 2 is a plan view showing parts in section. Fig. 3 is a vertical. sectional view 011 line 3 3 of Fig. 2i Fig. 4 is a sectional view on line 4-4 of Fig. 1, showing the range or stove in plan view, showing the floor of the tank broken away to illustrate the flues therebeneath. Fig. 5 is a sectional view on line 5 5 of Fig. 1. Fig. 6 is a sectional view on line (i-G of Fig. 4. Fig. 7 is a sectional view on line 7-7 of Fig. 5. Fig.-8 is a diagrammatic view showing the course the heat takes in passing through the system to a roonror the like to be heated.

Referring more especially to the drawings, 1 designates a conventional form of range or cooking stove having a fire box 2 with the usual form vof grate 3 therein, and provided with an oven 4. In.the present instance, a suitable casing 5 is constructed of any suitable material, with oradjacent to the casing of the range or stove. The extreme lower back -portion ofthe casing 5 is provided with threecompartments 6, 7, and

duit 18, which makesa turn or bend at 19 in the compartment 7 and4 extends through the wall 20 of the range or stove, and into the ash-pit A21, and terminates under the grate 3,-thereby constituting means to carry cold air to and under the grate. The pipe f or conduit 18 may be provided with a dam- Y perfor controlling the coldv air.

Arranged in 'the flue. or passage 15 is a .f damper 22, which may be thrown to open or. closed positions by means of a rod 23 and hand member 24.-- When the damper 22 is open as shown in Fig. 6 clearly,the smoke and the like passes directly through the upper part-or portion 15a of the flue 15, and passes out through the chimney to the exteriorv atmosphere. However, should the damper 22 be closed, as shown in Fig. 7 clearly, the products of combustion pass through the opening 25, and through the opening 26 ofthe 4wall 27 of the casing 5, and upwardly through the flue 14, as indicated by the arrows 28 in Fig. 7. Said products of combustion after passing up through the ue 14 passes through the openvmediate the extreme back portion of the cas ing 5 (where said compartments 6, 7, and 8,

ino 29 at the upper part of the wall 30 and f full line arrows 31. The products of combustion, indicated by the full line arrows 31, pass through the opening 32 at the lower edge of the partition or wall 33, and then upwardly through the iiue 10, through the opening 34 at the upper edge of the wall or partition 35, and then downwardly through the flue 11, through the opening 36 at the lower edge of the wall or partition 37, and upwardly through the flue 12, as '.udicate by the dotted line arrows 38 in Fig. 3. The products of combustion pass'from the flue 12 through the opening 39 at the upper edge of the wall or partition 40, and then downwardly throughthe flue 13, into the compartment or chamber 16, and if the damper 41 (which is mounted in the upper part of the chamber or compartment 16) is open, the products of combustion pass through the passage 42, into the upper portion 15a or fiue (which rises from the chamber or compartment 1,5) and passes out through the chimney to the exterior atmosphere. 'By means of this passage of the products of combustion, the water in the chamber or compartment 48 is thoroughly heated, and may be carried olf by means ofA the pipe 44 to" any suitable `service location for use. The pipe 44 is provided with a valve for con trolling the flow of heated water to the service location. i

Arranged ii on and forming a part of thc upper plate o the range or stove is an auxiliary casing 46 forming a warming or heating chamberfji?, there being an opening 48 in the top wall or Oven plate 49, to car the heat from the oven into the warmi'ng c amber, in which articles of food that have been cooked on the range or stove may be placed, to be kept warm until used. The heat from the warming chamber 47 passes through the opening 50 into the passage or flue 51, and should the dam r 52 be open, the heat from said warming c amber will pass'out throutgh the fiue 51 to the atmosphere, but should e damper 52 be? closed, as indicated at a in Fig. 1, the heat from said warming chamber will pass out through the pipe or conduit 53, und exit throu h a grate opening 54 into a room 55, as ini icated in dotted lines in Fig. 8. The foul air in the room 55 isdes ed to pass through the grate opening 56 ow through the pipe or conduit 57, and into the compartment 17 of the casing 5, and then upwardly through the passage 58 through thc 'fluo 59, and out through the chimney to thc exterior atmos here. A pipe or conduit (3() is provided wi i a valve 61, and leads or muuuunicutcs with the water chamber 43, for Asupplying water therein. Extending dou-woolly through the chambers or compartments 3, 7, :ind 8, and having their uppor :sul \.-onnnunifating with the lower porlions nl'. the flllcS l0, 11,:1Ild 12 are pipes 0l' conduits 62, through which suitable means In a heating system of the kind set forth,

the combination of a range or stove and a casing constructed to the rear and as a part of said range, of a water chamber in the upper part of the extreme back portion of said casing, said casing having a chamber at its lower art in communication with the fire pot of the range, said casing having a flue extending direct from said chamber to and in communication with the atmosphere, said casing having a second flue in communication Withjeaid chamber merging into an upwardly and downwardly zigzag ue having several bends under the water chamber, and terminating in a chamber in the lower part of said casing, said chamber in the lower part of said casing havn? a port of communication with the first ue, said first flue where it merges from its chamber havin n damper, to be opened or closed, where y the heat may leither pass through the first fiue or the second and zigzag dues, said last named chamber where it has a port of communication with the first flue having u damper, to be opened when the first damper is closed and vice versa. f

In testimony whereof I have signed my mung. to this specification in the prence of 80 two subscribing witnesses.
